Some screens of nvidia-settings:

Is there any way to beat the problem?

Not a problem at all.
The actual message is:

    39.035] (II) NVIDIA(0): Display (LG Electronics W2442 (DFP-0)) does not support NVIDIA
    39.035] (II) NVIDIA(0):     3D Vision stereo.

which means that this is no 3D display, i.e. one where you could have “real” 3D with 3D-glasses.


You should not need an xorg.conf at all, so just try to remove it.


I see no problem in there. The driver is loaded and appears to be working.

Is there any way to beat the problem?

Could you please describe your actual problem in more details?
What exactly do you mean with “low performance”?

And which Desktop Environment are you using?
If it’s KDE, have a look into “Configure Desktop”->Desktop Effects.
In “Advanced”: Composite type should be set to “OpenGL” (2.0 or 3.1), Qt graphics system should be set to “Raster”.

First of all thank you very much for the quick answer.

When I talk about low performance I mean slow image rendering when scrolling web pages in Firefox or noticeable defects during watching video.

I deleted the xorg.conf. Nothing changed. OpenGL was set to 3.1 from 2.0. Qt were and is raster.
Video is getting much better. Page scrolling remains bad (riffled).

Lost images if they help:

The pain for me is slow image rendering.

You might try different settings for “Tearing Prevention”.

Is it better when you disable desktop effects completely? (press Shift+Alt+F12 for temporarily disabling them)

Install the package “Mesa-demo-x” and post the output of this to see whether direct rendering is working for your user:

glxinfo | grep render

No. I can’t reach any images via those links.
